SPECIFICATION forming part of Letters Patent No. 345,068, dated July 6,1886.

Application filed April 30, 1886. Serial No. 200.729. (No model.) I

To all whom, it may concern..-

Be it known that l, FREDERICK THEODORE MILLER, of Fredericksburg. in thecounty of Spottsylvania and State of Virginia, have invented anew andusefulImprovementinSulky- Plows, of which the following is aspecification.

My invention consists in the improved construction, arrangement, andcombination of parts of a reversible sulky-plow, aswill be hereinafterfully described, and pointed out in the claims. g

Referring to the accompanying drawings, Figure 1 is a perspective viewof my improved sulky-plow, showing the right-hand plow lowered into itsoperative position, and showing in dotted lines the tongue adjusted toincrease the width of the furrow cut by the said plow. Fig. 2 isalongitudinal vertical sectional view taken on line xaaFig. 3. Fig. 3 isa rear elevation, and Fig. 4 is a perspective detail view, of theadjustable tongue attachment.

The same letters of reference indicate cor responding parts in all thefigures.

Referring to the several parts by letter, A represents the main frame ofmy improved. sulky-plow, the said frame being supported on the axle B,which has at its ends the usual wheels, 0 O. The rear end of this frameA is provided with the three parallel uprights D E F, and at the top ofthese uprights is secured the seat G, of suitable construction.

Between the converging forward ends of the side pieces of the frame Aare pivotally secured by means of the transverse pivot-bolts H H theforward ends of two plow-beams, I J, and the rear ends of theseplow-beams fit and slide between the central and outer paralleluprights, D, E, and F, which form guides for the rear ends of theplow-beams, and to these plow-beams, near the rear ends thereof, aresecured the right and left plows K and L, the plow K having itsmold-board on theright side, as shown, and being secured to therighthand'plow-beam, I, while the plow L has its mold-board on the leftside, and is secured to the left-hand plow-beam, J.

The mechanism for lowering whichever plow it is desired to use into itsoperative position and for raising the same when the other plow is to beused, is as follows: On the forward side of the uprights D E F arejournaled in suitable bearings two short transverse shafts, M N, theinner ends of these shafts being journaled in a bracket on the innerupright, E,'while their outer ends pass through the center of disks 0 O,rigidly secured to the outer edges of the outer uprights, D and F, andon that portion of each shaft which extends across the space between thecentral and outer uprights is rigidly secured an arm, P, to the free endof which is pivoted the upper end of a short pitman, Q. which ispivotally secured at its lower end in the rear end of its respectiveplow-beam.

.To the outer end of each of the adjustingshafts M N is secured thelower end of a handlever, B, which extends up within convenient reach ofthe drivers seat; and this hand-lever is provided with a spring-catch,S, adapted to engage with the forward aperture or notch, T, or the rearseries of apertures or notches, U, formed in the peripheries of thedisks 0 O, by which arrangement the lever is secured in its adjustedposition; and it will be seen that by pushing forward and downward thefree end of either hand-lever it will. operate to raise the rear end ofthe plow-beam to which it is connected, as described, while by throw.-ing back either the right or left hand lever either the right or lefthand plowcan be lowered into its operative position, the springoatch ofthe hand-lever being caught into any one of the series of apertures ornotches U, according to the depth to which it is desired to cut thefurrow.

Upon the forward end of the frame A, to which the side pieces converge,is secured a metallic frame, V, having the bottom flanges, V, forattachment to the main frame, and being formed with the cross-bars X andY, and in this frame fits the forward portion of the lever Z, the saidforward portion being forked to adapt it to receive the rear end of thetongue A, and having at this forward forked end the series of transverseapertures B, through which passes a transverse bolt, 0, which securesthe rear end of the tongue in the said forked portion of the lever, and,the tongue at that point being of less thickness than the height of thejaws between which it is secured, it will be seen that its outer end maybe raised or lowered and secured in its adjusted position by the bolt 0,so as to regulate the depth of the furrow cut by the plows, or to suitthe height of tongue to the height of the horses drawing the plow. Avertical bolt, which forms the king-bolt, (as it also secures thedoubletree E upon the forward cross-piece, X, of the frame V,) passesdown through the said crosspiece and through a short vertical slot, F,in the rear end of the tongue A, forming a pivot on which the tongue andlever may be swung from side to side to increase the width of the furrowbeing cut, the rear end of the pivoted lever being upturned and providedwith a spring-catch which engages with any one of a series of apertures,G, formed in the rear crossbar, Y, of the metallic frame V; and it willbe seen that by this arrangement the lever may be swung from side toside, so as to adjust the tongue to either the right or left hand side,so as to regulate the width of the furrow and always keep the tonguestraight between the horses and perfectly equalize the draft, and as thedouble-tree is on the top of the case or frame V and separate from thetongue there is no side draft whatever on the tongue, leaving it looseand balanced on its pivot-pin, so that the tongue can be adjusted evenwhile the team is in motion.

In operation the tongue is adjusted at the right angle through themechanism just described, and either the right or left hand plow loweredinto its operative position,according to the direction to which thesulky-plow is being driven across the field. At the end ofa furrow theplow is raised, the vehicle turned to return across the field, and theother plow lowered, so that the earth from each furrow is always turnedby the mold-boards in one direction. The lower end of the centralupright at the rear end of the main frame A is extended down to form aguide for the two standardplows, as clearly shown in Fig. 3 of thedrawings. The double-tree is further held in position by the hingedcurved plate or follower H, through which the king-bolt also passes.

From the foregoing description, taken in connection with theaccompanying drawings, the'construction, operation, and advantages of myimproved reversible sulky-plow will be readily understood.

It will be seen that my improved plow is simple in construction, and istherefore not liable to break or get out of order, while at the sametime it is very efficient in its operation. By its use I can turn aperfect furrow on hillside or level ground.

I am aware right and left plows have been attached to beams pivoted attheir forward ends; also, that levers and pivoted rods have beenemployed to elevate such beams at the rear end, and that plow-tongueshave been pivoted and provided with pivoted levers for adjusting themlaterally. My invention, therefore, lies in certain novel details ofconstruction and combination of parts, as specified in the followingclaims.

I claim 1. The combination. with the plow-frame, of the metallic pieceV, secured to the front end of the same, and having the aperturedcross-bar Y,the tongue A, pivoted as specified, the lever Z, attached tosaid tongue, and a spring-catch attached to the lever, whereby thetongue may be adjusted at different angles and secured in each adjustedposition, as shown and described.

2. The combination, with the pivoted plowbeams and the fixed paralleluprights, of the pitman Q and the separate but aligned transverse shaftsM M, having fixed radial arms P, and hand-levers R, the apertured disks0, fixed on the uprights, and the springcatches S, attached to saidlevers and adapted to en gage with the disks, all as shown anddescribed.
